Completing The Test - ABB RET670 Commissioning Manual

1MRK 504 154-UUS B
No delayed operation of zone 1 must be observed.
6. Configure the PUPSD functional input to connect to the PICKUP functional output and repeat
the previous fault.
Fast trip, caused by the operation of zone 1 must appear with a time delay, which is equal to
the set time delay on the timer
functional output signal, which must appear for a short time.
7. Be sure to establish the original configuration of the IED and the original settings of all
setting parameters.

Completing the test

Continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.
10.4.11 Pole slip protection PSPPPAM (78)
Prepare the IED for verification of settings as outlined in section
"Preparing for test"
10.4.11.1 Verifying the settings
It is assumed that setting of the pole slip protection function PSPPPAM (78) is done according to
impedances as seen in figure
The test is done by means of injection of three-phase current and three-phase voltage from a
modern test device. This test device shall be able to give voltage and current with the possibility to
change voltage and current amplitude and the angle between the injected voltage and current. The
parameter setting shall be according to the real application chosen values.
Procedure
1. Feed the IED with current and voltage corresponding to a normal operation point
Injected voltage V equal to base voltage (
base current (
2. With maintained amplitude of the injected voltage the current amplitude and angle is
changed to a value ZC/2.
This is done with a speed so that the final impedance is reached after 1 second. As the
injected voltage is higher than 0.92
3. With reduced amplitude of the injected voltage to 0.8
is changed to a value ZC/2.
This is done with a speed so that the final impedance is reached after 1 second. As the
injected voltage is lower than 0.92
4. With reduced amplitude of the injected voltage to 0.8
is changed via ZC/2 to a value corresponding to half
current and voltage.
This is done with a speed so that the final impedance is reached after 1 second. As the
injected voltage is lower than 0.92
to this the signal ZONE1 should be activated.
